Do you know what causes tenosynovitis?

Tenosynovitis is a very common disease in daily life, which makes people feel very worried, wondering whether it will seriously affect their physical health. The main causes of tenosynovitis include exogenous wind-cold, liver and kidney deficiency, insufficient qi and blood, and accumulated strain. It is usually divided into myosynovitis, radial styloid styloid tenosynovitis, ulnar wrist extensor tenosynovitis and flexor tendon stenosing tenosynovitis according to different symptoms. Patients need to choose the appropriate treatment method according to their own symptoms. Only in this way can they recover their health as soon as possible and get rid of the troubles of this disease.

1. What are the main factors that cause tenosynovitis?

1. Exogenous wind-cold: Fingers exposed to cold stimulation are also prone to tenosynovitis, which can cause blood stagnation, blood stasis, and pain, leading to the onset of tenosynovitis.

2. Liver and kidney deficiency, insufficient Qi and blood: With age, the essence of the liver and kidney declines, Qi and blood are insufficient, the muscles around the fingers lose the nourishment of Qi and blood, the flexor tendons of the fingers degenerate, the secretory function of the synovial sheath decreases, and slight external stimulation can lead to inflammation of local tenosynovitis.

3. Accumulated strain: excessive finger work, frequent flexion and extension, accumulated strain and injury to the tendons, repeated friction and compression of the flexor tendons in the bony fibrous tubes; or long-term forceful holding of hard objects, compression of the bony fibrous tubes between the hard objects and the metacarpal bones, resulting in local congestion and edema of the bony fibrous tubes.

The above content is an introduction to "What are the main factors that cause tenosynovitis". I hope these contents can help more patients. Regarding other common knowledge about this disease, the following is an introduction for you, and I hope you will have a better understanding of this disease.

2. What are the common symptoms of tenosynovitis?

1. Myosinitis is also known as gravel myosinitis: when the wrist activity increases, redness, swelling, heat, and local tenderness appear on the proximal side of the back of the wrist, and pressure may produce crepitus or snow-stepping sounds.

2. Radial styloid stenosing tenosynovitis: also known as de Ouervains disease, its characteristic manifestation is pain on the radial side of the wrist joint and is closely related to thumb movement. This disease is more common in women over 40 years old, but it can also occur in breastfeeding women.

3. Ulnar wrist extensor tenosynovitis: It is one of the causes of ulnar wrist pain. The extensor carpi ulnaris tendon and surrounding sheath play an important role in supporting the distal radioulnar joint and the triangular fibrocartilage complex of the wrist. When the wrist is too active, repeated pulling or spraining may induce pain on the ulnar side of the wrist, especially soreness and weakness in the wrist when exerting force.

4. Stenosing tenosynovitis of the flexor tendon: It often occurs in the thumb, middle and ring fingers, and the age of onset is generally over 40 years old. In the early stage of the disease, snapping and pain occur when the fingers are flexed and extended, so it is also called "trigger finger". Patients often report inflexible joint movement and swollen joints. In severe cases, the joint is locked in flexion or extension, and the joint cannot be straightened or flexed. This disease occasionally occurs in children, with the thumbs on both sides in a flexed position and unable to be actively straightened. In mild cases, the thumb can be straightened through local massage when the child is asleep. In severe cases, the thumb cannot be straightened even passively.

3. What are the harmful manifestations of finger tenosynovitis?

1. The tendon sheath is located near the joints of the hands and feet, around the long tendons of the muscles. Because these parts are frequently active and have many chances of injury, if you are not careful, long-term friction, chronic strain or cold stimulation can cause aseptic inflammatory reactions in the tendons and tendon sheaths. Symptoms of finger tenosynovitis include local exudation and edema. Over time, the tendon sheath will become ossified, the sheath wall will thicken, and the lumen will be narrowed.

2. The symptoms of finger tenosynovitis often occur on the palm side of the fingers. Common symptoms of finger tenosynovitis include redness, swelling, pain, and heat in the affected fingers, which are in a flexed state, because straightening the fingers will cause pain. If not treated in time, after purulent infection, tendon necrosis will cause the fingers to lose their function of movement, and pus can also flow into the adjacent finger tendon sheaths and palm gaps. The harm of finger tenosynovitis will cause complete disability of the hand. Patients with tenosynovitis may feel generally unwell, with chills and high fever.
